It's based on an earlier version of the "real" backend. It is a=20 SANE backend, and the IScan software uses the Sane protocol to=20 talk to this backend. So technically it is a Sane frontend. If you want to use IScan and Sane on the same machine, you can use a shell script wrapper for IScan that first sets the=20 LD_LIBRARY_PATH so that it finds the iscan libraries. >=20 > First, I installed SANE from sources below /usr/local and the Kawa thing > from the RPM, giving me 'can't send command to scanner' messages due to > a) a Bug in the SANE epson.c (Patch enclosed) The reset() function should never be called when the scanner device is not open. At least I am not aware of a situation=20 where this would happen.

The option name used by IScan is what I used with Sane 1.0.5, but changed since. I am however considering going back to the old syntax and using two hardcoded gamma values agan (1.0 and 1.8).

EPSON KOWA just released a new version, and I wanted to wait for this before I merge their changes back into my backend.
